摘要： The present invention is directed to a method and apparatus for making nanofiber webs, wherein a source of process air is utilized to affect the spray pattern and quality of fibrillated material expressed from a die assembly including a multi-fluid opening. Appropriately, the aforementioned process air is defined herein as an alternate or ancillary air source apart from primary process air, which primary air is simultaneously supplied with the molten polymeric material to the fiber forming multi-fluid opening. The ancillary air source of the invention is further distinct from secondary air, which is also known in the art as quenching air. The ancillary air can be described as a continuous fluid curtain of shielding or shaping air.

摘要： A nonwoven fabric comprises continuous polymer filaments of 0.5-3 denier that have been hydroentangled in a complex matrix of interconnecting filament loops, and that is otherwise substantially free of knotting, or of otherwise wrapping about one another. A process for making a non-woven fabric comprises continuously extruding polymer filaments of 0.5-3 denier onto a moving support, pre-entangling the filaments with water jets, and entangling filaments with a second set of water jets. An apparatus for making a nonwoven fabric comprises means for continuously extruding substantially endless polymer filaments of 0.5-3 denier onto a moving support to form an unbonded web, a pre entangling station for entangling the web with a plurality of water jets, and a plurality of water jets for final entanglement of the filament web.
摘要翻译：非织造织物包括0.5-3旦尼尔的连续聚合物长丝，其已经在相互连接的细丝环的复合基质中水解缠结，并且否则基本上不会打结或以其他方式彼此缠绕。制造无纺布的方法包括将0.5-3旦尼尔的聚合物长丝连续挤出到移动的载体上，用水射流预缠绕长丝，以及用第二组水射流缠绕长丝。一种用于制造无纺织物的装置包括用于将0.5-3旦尼尔的基本上环状的聚合物长丝连续挤出到移动的支撑件上以形成未粘合的网的装置，用于用多个水射流缠绕网的预缠绕台，以及多个水龙头用于纤维网的最终缠结。
